orange warning light 1992 180e
 

hi all. the past two days i have had a orange/yellow rectangular shaped warning light appear on my car & i dont know what the car is trying to tell me. so, the far right warning indicators are in the following order L-R: lights, battery, brakes, handbrake, oil & coolant. on the right side of the trip counter is this mysterious orange/yellow warning light with no symbol & right of that is the window washer warning light. the car manual does not mention my problem.
can anyone help
